How about a mini omega drill?
Using exactly the same but with green circuits, normal engines, red belts and ofc electric mining drills?
could be the same size but less speed or other balances ... and with the tech research to unlock this beast? could help a litle earlier i guess... plastic is hard to get when oil is not near and express belts ... well just a suggestion xD
Thank you very much...
Cheers ^_^
